Give the BNAT exam to get a 100% scholarship for BYJUS courses Solution The correct option is D 0%The red and white-flowered plants of Mirabilis jalapa exhibit incomplete dominance in the inheritance of flower colour, due to which they produce pink-flowered plants upon hybridisation. If pure breeding red-flowered plants are represented as ‘RR’ and pure breeding white-flowered plants as ‘rr’, then the pink-flowered plants are ‘Rr’. A cross between ‘Rr’ and ‘rr’ would produce pink-flowered plants (Rr) and white-flowered plants (rr) in the ratio of 1 : 1 Hence, there are zero chances of getting a red-flowered plant.
